Accessing the parameter bits
Parameter bits P0 ... P3 provide diagnostic information to the master for slave 2. Here, P0 ... P2
define whether a status query of code C00150 or an error/warning diagnostics is returned as slave
response to the master.
The values of P0 ... P3 are transmitted to the master via the "Write_Parameter" command.
